SPECIFICATION formingpart of Letters Patent No. 593,041, dated November 2, 1897.

Application filed September 5, 1896. Serial No. 605,036. (No model.)

To OLZZ whom it may concern:

Be it known that I, MARK BEADLE, a citizen of the United States, residing at the village of Climax, in the county of Kalamazoo and State of Michigan, have invented a certain new and useful Windmill Coupling Device, of which the following is a specification.

My invention relates to coupling devices, and more particularly to coupling devices for windmills and pumps. As heretofore constructed coupling devices of this character have been awkward to manipulate for the reason that the pump-handle and the windmill pump-rod were manipulated entirely separate, and if there was not a period at which they were both coupled to the piston-rod of the pump at the same time the piston-rod was likely to drop into the well and cause no little annoyance in its removal. An unnecessary amount of time is also consumed in the manipulation of the device.

The objects of this invention are to provide a device which shall be to a large extent automatic in its operation, which requires very little skill to manipulate, and which in coupling or uncoupling releases or engages the pump-handle or the pump-rod of the windmill at the same time it releases or engages the opposite part.

Further objects will appear definitely in the detailed description.

I accomplish these objects of my invention by the devices and means described in the following specification and illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the top of the pump and the lower portion of a pumprod of a windmill with one of my improved coupling devices in place. Fig. 2 is a side elevation of the same. Fig. 8'is an enlarged detailed sectional view on line 3 3 of Fig. 2, showing the coupling-pin through the pumprod. Fig. 4 is an enlarged detail transverse sectional view on line at 4 of Fig. 2. Fig. 5 is an enlarged detail transverse sectional view on line 5 5 of Figs. 1 and2. Fig. 6 is an enlarged detail transverse sectional view on line 6 6 of Fig. 2. Fig. 7 is an enlarged detail sectional view on line 7 7 of Fig. 3. Fig. 8 is an enlarged detail sectional view on the same line as the view in Fig. 3, showing the coupling-pin withdrawn and locked in place by the key. Fig. 9 is a detail view of a modified construction of the retaining-key for the coupling-pin.

In the drawings all of the sectional views are taken looking in the direction of the little arrows at the end of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is the pump.

B is the piston-rod of thepu mp, which Will be referred to hereinafter as the pump-rod.

B" is the windmill pump-rod or the rod in the windmill which connects the pump-rod.

The pump-rod B extends up through a suitable guide A on the pump and into a slide B on the bottom of the windmill pumprod. To the slide B, which is a portion of the windmill pump-rod proper, is secured by a suitable collarO myimproved coupling device. A bar in sections D D extends down by the side of thepump-rod B and is connected to the pump-rod B by a suitable clamp. The section D of the bar slides in a suitable guide in collar 0. The sections of the bar D Dare secured together by a collar E, containing the key E, which clamps the two together, as clearly appears in Fig. 4. A lever F is pivoted at a on the collar E and extends lengthwise of the pump-rod. Thimbles G are movably supported toward each end of the lever F, which extends through suitable slots in the same. The thimbles are also in suitable tubular guides G. The upper guide G is secured to the section D of the bar and the lower guide G is secured to the section D of the bar.

Supported in the thimbles G are the coupling-pins I, having spherical heads I to re tain them in the contracted ends of the thimbles. A spring M between the upper end of lever F and section D of the bar tends to throw the lever out and consequently always tends to throw the bottom end in and puts constant pressure on the lower pin I.

A block K, with a strap N at the back and a plate J in front, makes up the lower collar connection. The section D is held between the plate J and block K. In a suitable recess in block K next to the pump-rod Bis a movable slide or key L, (see Figs. 3, 8, and 7,) positioned to drop between the point of pin I and the pump-rod B when the pump handle A is uncoupled. This through its action holds the upper coupling-pin I in place and couples the pump-rod to the windmill pump-rod. The block K is extended downwardly and outwardly to serve as a guide for the ends of the pump-rod in coupling the pump-handle in. The thickness of the key L is a little greater than the portion of the pumphandle to that side, so that merely sliding the pump-handle to place pushes the key up and releases the pin Iat that point and allows it to pass through the handle and pump-rod, coupling them together. This through the connection with lever F withdraws the pin from the slide and pump-rod above and uncouples the windmill from the pump.

When it is desired to again couple the windmill and pump, the pump-rod and with it the coupling device is raised by the pumphandle till the upper pin I comes opposite the hole T in the slide B,when the pin is inserted by pressing it in, which as soon as it couples draws the lower pin from the pumphandle a and allows the pump-handle to be withdrawn, when the key L drops and holds the pin in the disengaged position automatically. Thus it will be seen that my improved coupling for wind mills is very easy to operate and it is very effective and saves all the inconvenience and annoyance heretofore experienced.

In Fig. 9 I have shown a modified form of key or look L, which is pivoted to the block K, an arm of which is indicated by dotted.

lines as extending in front of the look L. This lock has aslight advantage over the form shown in the main drawings in that it is actuand does not depend on the action of gravity at all.

Having thus described my improved coupling device, I desire to state that it can be greatly varied without departing from my invention.

The form of the pins can be changed. The guiding-bar D D can be in a single piece. It is made in two pieces, as indicated, to accommodate the device to different sizes and styles of pumps where the holes in the pump-rod vary in their distance apart. The form of the slides can be varied also.

The form in which I have shown my device is the form preferred by me and possesses great merit.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
